Mila Kunis and Ashton Kutcher might have a fairytale marriage but the beautiful actress confessed that their honeymoon was more like a nightmare.

In an interview with Jimmy Fallon on the Tonight Show on Monday night, the 34-year-old said they both exclaimed 'I quit' following a series of blunders three years ago.

Mila told Jimmy the honeymoon was like a 'real life National Lampoon movie,' saying her first 'boo boo' was when she bought her husband, 40, an RV so they could go on a road trip with their in-laws and their 10-month-old daughter Wyatt.

Mila said she bought a 'little tin can on wheels' and as they neared Los Angeles, the RV's air-conditioning broke down in '110 degree weather.'

But that was not all. She said: 'We almost died on the side of the road when Apple Maps took us on a road ... it wasn't a road.

'It was a fire road on the side of a mountain. We all had to jump out of the vehicle and walk for like three miles while my father-in-law drove the van.

She said: 'We almost died on the side of the road when Apple Maps took us on a road ... it wasn't a road' (pictured with her husband in December 2017)

'Ashton navigated him over gigantic boulders because there had just been a massive flood.'

She continued: 'The breaking point came when Kutcher's mom used outdated travel books to find them RV parks near Napa Valley.

'We ended up in an area "an hour outside Napa, with two prisons. That is where our TV trip ended".

She said: 'My husband looks at me and goes, "I quit," and I was like, "Me too".'

Mila and Ashton met on That Seventies Show - it ran from 1998 until 2006, but the actors did not fancy one another during this time.

The star never saw him as anything other than a friend until she met up with him years later at an awards show but unfortunately, when he invited her to a party, it was actually to introduce her to his pal.

She said: 'We'd always kept in touch but I never thought of him romantically. I was at an awards show and I see this guy and I see his back and he's really tall.

'I was like, "Who's that guy?" Then he just turns around and it was literally like if we were in a movie, the music would start playing and the violins would go...I think for the first time ever he took my breath away...I was like f**k, he's good looking.

'He had planned to set me up with his friend. Long story short, I didn't leave until the next morning. It was the first time I had stayed over at a guy's house when I was single but he didn't want me to leave.'

After a series of terrible luck on their trip, Mila said: 'My husband looks at me and goes, "I quit," and I was like, "Me too"'
